; unrrnnsira rns rATEN QFFIC tacos HAISH COMPANY,

WAGON-SCALE. 4 I

of Illinois, have invented certain new and 'useful'lmprovements 1n WVagon-Scales, .of

which the following is a specification.

, My invention pertains to wagon scales, of that class wherein a load supported on carrying-wheels for the purpose of transportation from. one point to another, may be weighed by mechanism carried upon the wagon. In order to do this the weight .of the load is transferred from themain frame of the wagon to mechanical parts by which the I consist in those parts bywhich the weight of the load is transferred from the main frame to the weighing mechanism and the reverse.

In he drawingsz'Figure 1. is a plan view of a machine equipped with my device. Fig.

i 2 is a detail, showing one of the bolster engaging devices. Fig. 3 is an enlarged detail showing the means for operating the device.

1 represents the main frame, upon which a pair of bolsters 2 normally rest, such bolsters being capable, of supporting the usual wagon body. (Not shown); The frame 1 is also adapted to be supported on the bolsters of the usual running gear of a wagon. Pivoted in-the sides of the frame 1, as at points a, is a pair of frame levers 3, provided with outwardly projecting arms 4, each of which is provided with a threaded perforation in which is held a similarly threaded screw 5, adapted to cooperate with a pin 6 in the end of the bolster 2. Such pin is preferably pointed and the end of the screw provided with a slight depression to receive the same. On the lower ends of the screws 5 are secured sprocket-wheels 7, pass- I ing around which is a sprocket-chain 8,

the shaft 14 is a, sprocket-wheel 15, in operative position with reference to the chain 8. Mounted in theframe 9 is a guard-roller 16, which prevents the chain 8 from becoming disengaged with the wheel 15. Upon the shaft 10, being suitably rotated by means vof the crank 11 the wheels 7 are rotated to cause an upward movement'of the Specification of Letters Patent, Patentgd A 2'? 1915 Application filed December 11, 1914. Serial No. 875,660. r 1

screws 5, as above mentioned. A continued upwardmovement of such screws results in the bolsters 2 being raised from contactwith the frame 1, until such bolsters, and the weight sustained thereby rest entirely upon the outer ends of the frames 3. I Transversely'. of the frame 1 1s secured a pair of bars 17 supporting brackets 18, be

tween which is fulcrumed a lever 19, as at I).

The outer end of said lever is connected in i any suitable manner with the short end of a scale-beam 20, pivoted on theside of the frame 1, and the inner en'd of said lever is connected by means of links 21 with the inner ends of the framedevers When the weight'of the load on the bolsters 2 is transferred to the frames 3, in the manner above described, such weight is thereupon impart ed through said frames and-the lever 19 to theweighing mechanism, to be indicated thereon. After being weighed, by a reversal of movement of the'crank 11 the screws 5 are again moved downwardly until the bolsters and load against rest upon the frame 1, in which position they are normally held.

The chain 8 is preferably provided with a turn-buckle 22, by means of which any slack in the chain may be taken up. Such chain moves up or down freely with the outer ends of the frames 3, and the weight of the chain or other parts is counterbalanced by other parts of the mechanism, or by usual counterbalancing means on the scale-beam.

What I claim as my invention, and desire to secure by Letters-Patent of the United States is:

1. A device of the class named, comprising a main frame, suitably supported; bolsters normally supported on said frame; frame-levers pivoted in said frame and provided at their outer ends with screws adapted to cooperate with said bolsters to raise the same from said frame; weighing devices mounted on said frame and operatively connected with the inner ends of said frame levers; and means for simultaneously operating said screws, to raise said bolsters and transfer the load thereon from said main frame to said frame-levers.

2. A device of the class named, comprising a suitably mounted main frame; loadcarrying means normally supported thereon; frame levers pivoted in said frame; screws vertically movable in the outer ends of said frame levers, adapted to cooperate with said load-carrying means to elevate the same above said frame; and provided with similar sprocket-wheels; a sprocketchain engaging all of said sprocket-wheels, so as to impart rotation thereto simultaneously; weighing-devices mounted on said frame; and operatively connected with the inner ends of said frame-levers; and means for suitably actuating said sprocket-chain.

3. A device of the class named, comprising a suitably mounted frame; load-carrying means normally supported thereon; frame-levers pivoted in said frame, and provided at their outer ends with screws capable of vertical movement to engage said load-carrying means to raise the same from said frame; sprocket-wheels fixed on said screws; a sprocket-chain engaging said wheels and adapted to actuate the same simultaneously; means for suitably operating said chain; weighing mechanism mounted on said frame; and a lever connected with said weighing mechanism and operativelyconnected with said frame-levers.

4:. A device of the class named, comprising a suitably mounted frame; load-carrying means normally mounted thereon; frame-levers pivoted in said frame; screws in the outer ends of said frame-levers adapted to operate vertically to raise or loweri said load-carrying devices; sprocket-wheels fixed on said screws; a sprocket-chain engaging said sprocket-wheels and capable of operating the same simultaneously; handoperated gearing at the side of said frame adapted to suitably actuate said chain; weighing mechanism mounted on said. frame; and a lever fulcrumed in said frame, connected with said weighing mechanism, and operatively connected with said frame levers.

5. A device of the class named, comprising a suitably mounted frame; load-carrying devices normally supported on said frame; frame levers fulcrumed in said frame; screws vertically operable in said frame-levers, and adapted to cooperate with said load-carrying devices, to raise or lower the same; sprocket-wheels fixed on said screws; a sprocket-chain engaging said sprocket-wheels to simultaneously operate the same; manually operated means at the side of said frame for actuating said chain; means for taking up the slack in said chain; weighing mechanism mounted on said frame; and a lever fulcrumed in said frame, connected with said weighing mechanism and operatively connected with said framelevers.

In testimony whereof I afiix my signature in presence of two witnesses.
